For example, a user may instruct comparison module 112 to compare one or more columns of data from the source data location to one or more columns in the target data location. Comparison module 112 may then use this information to map data from the source data location to data contained at the target data location. As an example, a user may specify to comparison module 112, using GUI 136, that a particular column in source database 160 corresponds to a particular column in target database 150. In certain embodiments, comparison module 112 may use a data mapping file to map data from the source location to data stored in the target location. The data mapping file may be stored with files 170, memory 134, memory 104, or any other storage location suitable for a particular purpose.

Comparison module 112 may also be capable of comparing data from a source data location to data in a target data location by executing a particular SQL query or queries. Executing a particular SQL query may access some or all data stored in one or more databases. For example, a user may specify the path of input file 170 containing one or more SQL queries that can be used to compare data. Using a specified SQL query, comparison module 112 can then execute the comparison SQL query and determine whether the data contained in the source data location matches the data contained in the target data location. Additionally, comparison module 112 may be capable of combining data from the source data location and data from target data location into one set of data. For example, a user may desire to compare data from the source data location to data in a target data location and then output all data that matches. A user is able to specify to comparison module 112, using GUI 136, which portions of the source data location should be combined with which portions of the target data location.

Data processing environment 130 may also include reporting module 114. Reporting module 114 may be any combination of software, hardware, and/or controlling logic that allows data processing environment 130 to communicate the results of any action undertaken by data processing environment 130 or any other component of data verification system 100.

Data update and verification module 116 may reside in data processing environment 130, workstation 110, or any other suitable component of data verification system 100. In certain embodiments, data update and verification module 116 may be software stored in memory 104. For example, data processing environment 130 may allow the user to access the various functionalities of data update and verification module 116 using GUI 136 of workstation 110. Generally, the purpose of data update and verification module 116 is to allow users to update table data and verify the updated data against expected results without having to write any SQL queries. For example, data update and verification module 116 is capable of updating one or more tables in a particular database. In certain embodiments, a particular database may be target database 150 or source database 160. Data update and verification module 116 may receive a particular source to update from a user using GUI 136 of workstation 110.

Data update and verification module 116 is capable of presenting various portions of the source data to a user allowing the user to select a certain portion to update. The user may use GUI 136 to select a specific portion of the source data to update. For example, a user may specify a table name in a database to data update and verification module 116. Data update and verification module 116 may display all the columns of a particular table. A user may use GUI 136 to select one or more cells contained in the in one or more columns in the source data and provide data update and verification module 116 with an updated data value for those one or more cells. In certain embodiments, data update and verification module 116 may be capable of storing expected data. For example, expected data may be some data that a user of data verification system 100 has deemed to be “correct” and is used as baseline data. Expected data can then be used by data update and verification module 116 or any other component of data processing environment 130 to compare or verify data. In certain embodiments, data update and verification module 116 may store expected data in file 170, in source database 160, or in target database 150. Data update and verification module 116 is capable of retrieving previously stored expected data for later verification and comparison of updated data.

Data verification system 100 may contain one or more databases. For example, data verification system 100 may contain target database 150 and source database 160. Target database 150 and source database 160 may be any repository capable of storing data. In certain embodiments, target database 150 and source database 160 may be a collection of interrelated tables in a relational database. Data verification system 100 may also contain one or more input files 170. Input file 170 may be a text file, an extensible markup language file, a collection of database SQL queries, a common separated values file, a spreadsheet, or any other format suitable for a particular purpose. For example, input file 170 may be any source of data to be processed, stored, or verified by data processing environment 130 or any other component of data verification system 100 suitable for any particular purpose.

Example operations of data verification system 100 will now be discussed. Data verification system 100 may provide a variety of functions. For example, data verification system may provide file parsing functionality through the use of parsing module 106. Parsing module 106 may be used to process particular data from a data source such as a database or a data file. In certain embodiments, parsing module 106 may process data from source database 160 or data from input file 170. Parsing module 106 may determine a source location of the data to be processed. In certain embodiments, a user may use GUI 136 of workstation 110 to specify a source location of data to be processed by parsing module 106. Workstation 110 may communicate message 126 to data processing environment 130. Message 126 may comprise a request to process a particular source of data. In response to message 126, parsing module 106 may access the particular source of data. Additionally, a user may use GUI 136 of workstation 110 to specify a data format of the source data. For example, a user may use GUI 136 to specify whether the data is delimited by a specific character and/or whether the data has a specific length. A user may also specify whether the source data includes a row of headers corresponding to columns in target database 150. Furthermore, a user may use GUI 136 of workstation 110 to specify information regarding target database 150. For example, a user may type in a particular table of target database 150 which will store the data from a data source.

Workstation 110 may communicate some or all information regarding the source data and target database 150 by communicating message 126 over network 120 to data processing environment 130. Parsing module 106 may then use information contained in message 126 to process the data from the source data according to the parameters specified by the user. After processing the data according to the user's specifications, parsing module 106 may then store the data at a target destination. For example, parsing module 106 may access input file 170 by communicating message 124 over network 120 to files 170. Message 124 may contain a request to access files 170. In response to message 124, parsing module 106 may access files 170.

Similarly, parsing module 106 may determine that source data is located in source database 160. Parsing module 106 may communicate message 122 over network 120 to source database 160. Message 122 may comprise a request to access source database 160. In response to message 122, parsing module 106 may then access data contained in database 160. Parsing module 106 may then process the source data according to processing information received from the user. Parsing module 106 may store the processed source data at a specified target location. For example, parsing module 106 may be instructed to store the processed source data in target database 150. Parsing module 106 may communicate message 118 over network 140 to target database 150. Message 118 may contain a request to store processed source data in a particular portion of target database 150. In response to message 118, processed source data may be stored in target database 150.

Another functionality provided by data verification system 100 is executing multiple SQL queries. Data processing environment 130 may allow a user to execute multiple SQL queries through batching module 108. Batching module 108 may receive a location containing one or more SQL queries. For example, a user may use GUI 136 of workstation 110 to specify a particular location of input file 170. Workstation 110 may communicate message 126 to data processing environment 130. Message 126 may comprise a request to process input file 170. In response, batching module 108 may access input file 170. Batching module 108 may then process input file 170. For example, batching module 108 may analyze the contents of input file 170 and extract one or more SQL queries from input file 170. Batching module 108 may then communicate message 126 to workstation 110. Message 126 may comprise a request to display the various contents of input file 170. In response, the SQL queries extracted from input file 170 may be displayed in GUI 136 of workstation 110. A user may then use GUI 136 to select one or more SQL queries presented in GUI 136. After selecting one or more of the extracted SQL queries from input file 170, a user may then instruct batching module 108 to execute the selected SQL queries. For example, a user may use GUI 136 of workstation 110 to select one or more SQL queries extracted from input files 170. Workstation 110 may then communicate message 126 to data processing environment 130, message 126 comprising a request to execute the one or more SQL queries contained in message 126. In response, batching module 108 may execute the SQL queries contained in message 126.

Data verification system 100 may also allow the comparison of two collections of data using comparison module 112. Comparison module 112 is capable of comparing one set of data to another set of data and outputting the results of that comparison. Comparison module 112 may receive a location for source data. In certain embodiments, the location of source data may be for input file 170 or source database 160. For example, a user may use GUI 136 of workstation 110 to specify a particular source file location. Workstation 110 may communicate message 126 over network 120 to data processing environment 130, message 126 comprising a source data location as well as a request to compare two collections of data. In response, comparison module 112 may gain access to data at the source location.

Comparison module 112 may then present the structure of the source data to a user. For example, comparison module 112 may communicate message 126 over network 120 instructing GUI 136 to display the structure of the collection of source data. In certain embodiments, displaying the structure of the source data may comprise displaying columns of the table containing the source data. The user may also specify a location of target data. In certain embodiments, the location of the target data may be the location for target database 150. The user may input the location of target data using GUI 136 of workstation 110. Workstation 110 may communicate message 126 over network 120 to data processing environment 130. Message 126 may comprise the location of the target data. Comparison module 112 may then, in response to message 126, access data at the location for target data. For example, comparison module 112 may take the location of a target data and communicate message 118 over network 140 to target database 150. In response, comparison module 112 may gain access to target database 150. Comparison module 112 may collect information regarding the structure of the collection of target data. After collecting this information, comparison module 112 may then communicate message 126 to workstation 110. Message 126 may comprise the structure of the collection of target data to be displayed in the GUI 136. In certain embodiments, the structure of the collection of target data may comprise the columns of the table containing the target data in target database 150.

A user may use GUI 136 of workstation 110 to signify which portions of the source data correspond to which portions of the target data. In certain embodiments, the user may use GUI 136 to select one or more columns of one or more tables containing the source data. The user can use GUI 136 to specify one or more columns containing target data, wherein the columns containing target data corresponding to the columns containing source data. Workstation 110 can communicate message 126 to data processing environment 130, message 126 containing the user's mapping of the structure containing source data to the structure containing target data.

A user may also specify one or more comparison SQL queries for data processing environment 130 to execute. For example, a user may specify a file containing one or more SQL queries using GUI 136 of workstation 110. Workstation 110 may communicate message 126 to data processing environment 130. Message 126 may include the file location of a file containing one or more comparison SQL queries. In response, comparison module 112 may access the file containing the one or more comparison SQL queries. Comparison module 112 may then instruct GUI 136 to display the one or more SQL queries contained in the file at the specified location.

A user can use GUI 136 to select one or more comparison SQL queries to compare the source data to the target data. For example, a user may use GUI 136 of workstation 110 to specify one or more comparison SQL queries. Workstation 110 may then communicate message 126 to data processing environment 130, message 126 including the one or more comparison SQL queries. In response, comparison module 112 may determine whether the source and target data match by executing the one or more comparison SQL queries. Furthermore, comparison module 112 may store the results of the comparisons in memory 104 or any other storage location suitable for a particular purpose.

After one or more functions have been performed by data processing environment 130, data processing environment 130 may provide results to a user via reporting module 114. For example, a user may use GUI 136 of workstation 110 to specify a destination for communicating results generated by the components of data processing environment 130 or any other component of data verification system 100. In certain embodiments, reporting module 114 may communicate results to a particular database. For example, a user may use GUI 136 of workstation 110 to specify a particular database to store results generated by any component of data processing environment 130. A user may type in the location of the particular database using GUI 136. Workstation 110 may then communicate message 126 over network 120 to data processing environment 130. Message 126 may comprise the location of a particular database to store the results as specified by the user.

In certain embodiments, reporting module 114 may store the results generated by a component of data processing environment 130 in a file. For example, a user may use GUI 136 of workstation 110 to input a file location to store results generated by a component of data processing environment 130. Workstation 110 may communicate message 126 to data processing environment 130. Message 126 may contain a location of a file where results should be stored. Additionally, a user may specify the results generated by a component of data processing environment 130 should be emailed to a particular email address. As such, a user may use GUI 136 of workstation 110 to specify that the results generated by a component of data processing environment 130 should be emailed to a particular email address. A user may input the email address using GUI 136 or the user may instruct data processing environment 130 to use an email address stored in a configuration file. Workstation 110 may then communicate message 126 over network 120 to data processing environment 130. Message 126 may contain a user's preference for email reporting. In response to message 126, reporting module 114 may communicate the results of a particular component of data processing environment 130 according to the user's preference. For example, a user may have specified target database 150 as the destination to store results generated by a component of data processing environment 130. Reporting module 114 may communicate message 118 over network 140 to target database 150. Message 118 may contain the results of a function implemented by data processing environment 130. In certain embodiments, message 118 may simply contain user preferences for reporting results generated by a component of data processing environment 130.

Data processing environment 130 may also allow a user to store, update, and/or verify particular data using data update and verification module 116. Data update and verification module may receive table information regarding a table and a database that might store a portion of data. In certain embodiments, a user may use GUI 136 of workstation 110 to specify a particular table that is the target location for storing certain data. Workstation 110 may communicate message 126 to data processing environment 130. Message 126 may contain information regarding a table which is the destination for storing data. In response to message 126, data update and verification module 116 may access the table and retrieve the structure of the table. For example, data update and verification module 116 may communicate message 118 over network 140 to target database 150. Message 118 may comprise a request to access the table specified by the user. In response to message 118, data update and verification module 116 may have access to database 150. Data update and verification module 116 may then communicate message 126 to workstation 110. Message 126 may contain information regarding the structure of the destination table. In response to message 126, GUI 136 may present a list of columns of the destination table to a user for selection of a particular column.

A user may use GUI 136 to choose particular columns of data for data processing environment 130 to retrieve. Workstation 110 may then communicate message 126 over network 120 to data processing environment 130, message 126 containing columns of the destination table selected by the user. In response to message 126, data update and verification module 116 may communicate message 118 over network 140 to target database 150. Message 118 may comprise a request to access the portions of database 150 containing the selected columns. In response to message 118, data update and verification module 116 may then have access to the data contained in the selected columns of target database 150. Data update and verification module 116 may then communicate message 126 to workstation 110. Message 126 may be a request to display the data in the selected columns in GUI 136. In response to message 126, GUI 136 may display the data of the selected columns of target database 150. In certain embodiments, this data may be presented as rows and columns with each intersection of a row and a column forming a cell of data. In certain embodiments, a user may repeat the process to add data from one or more columns of tables in target database 150.

Once a user has selected all the desired columns of tables stored in target database 150, a user may begin to select particular cells of data to update. For example, a user may use GUI 136 to select one or more cells of data to update. After selecting one or more cells, the user may enter a value that should replace the current value held in those particular cells. Workstation 110 may communicate message 126 to data processing environment 130 after the user finishes entering data to replace the data currently held in the selected cells. Message 126 may contain a reference to the particular cells that the user wants to update and the particular data that the user wants to store in those selected cells. In response to message 126, data update and verification module may communicate message 118 to target database 150 to update the selected cells according to the user's input.

In certain embodiments, a user may want to store a set of data that may be the expected results of a particular process. In such an embodiment, a user may use GUI 136 to communicate to data processing environment 130 that the data being entered into GUI 136 is intended to be set as the expected results data. Expected results data may be any data that is deemed to be “correct” data. Data processing environment 130 may then compare a particular set of data against the expected results data to determine whether the particular set of data is “correct” as well. In certain embodiments, if the data being stored by the user is not intended to be the expected result, data update and verification module 116 may store the data updates in an external file. For example, data update and verification module 116 may write the results into a file corresponding to the database structure of target database 150. Data update and verification module 116 may compare the data in this file to the data of target database 150 which contains the expected results data. If the data in the external file matches the expected results data held in target database 150, then data update and verification module 116 may deem the data in that file verified. Data update and verification module 116 may then output the results of this verification. In certain embodiments, data update and verification module 116 may communicate these results using reporting module 114.

The method may be implemented in any suitable combination of software, firmware, and hardware. Although particular components may be identified as performing particular steps, the present disclosure contemplates any suitable components performing the steps according to particular needs.

The example method begins at step 400. Parsing module 106 may be used to process particular data from a data source such as a database or a data file. In certain embodiments, parsing module 106 may process data from source database 160 or data from input file 170. Parsing module 106 may determine a source location of the data to be processed. In certain embodiments, a user may use GUI 136 of workstation 110 to specify a source location of data to be processed by parsing module 106. Parsing module 106 may determine whether the source location of data is a database or a file. If the source location is a database, the example method may proceed to step 404. Otherwise, the example method may proceed to step 402. At step 402, parsing module 106 may receive a file name. For example, a user may have specified a file name using GUI 136 of workstation 110. In response, workstation may communicate message 126 to data processing environment 130. Message 126 may comprise the name of a particular file to process. The example method may proceed to step 406.

At step 404, workstation 110 may communicate message 126 to data processing environment 130, wherein message 126 may comprise a request to process a database as a source of data. Message 126 may further comprise information regarding the database containing the data.

At step 406, a user may use GUI 136 of workstation 110 to specify a data format of the source data. For example, a user may use GUI 136 to specify whether the data is delimited by a specific character and/or whether the data has a specific length. Workstation 110 may communicate this information to data processing environment 130 via message 126. At step 408, data processing environment 130 may determine whether there is a column header row. For example, a user may specify whether the source data includes a row of headers corresponding to columns in target database 150. If there is a column header row, the example method may proceed to step 410. Otherwise, the example method may proceed to step 412. At step 410, data processing environment 130 may receive a particular row number of the source data that includes a row of headers corresponding to columns in target database 150. For example, a user may specify this information using GUI 136. Workstation 110 may then communicate this information via message 126 to data processing environment 130.

At step 610, after collecting this information, comparison module 112 may communicate message 126 to workstation 110. Message 126 may comprise a request to display the structure of the collection of target data to be displayed in the GUI 136. In certain embodiments, the structure of the collection of target data may comprise the columns of the table containing the target data in target database 150.

At step 612, a user may use GUI 136 of workstation 110 to signify which portions of the source data correspond to portions of the target data. In certain embodiments, the user may use GUI 136 to select one or more columns of one or more tables containing the source data. The user can use GUI 136 to specify one or more columns containing target data, wherein the columns containing target data correspond to the columns containing source data. Workstation 110 can communicate message 126 to data processing environment 130, message 126 containing the user's mapping of the structure containing source data to the structure containing target data.

At step 614, a user may specify one or more comparison SQL queries for data processing environment 130 to execute. For example, a user may specify a file containing one or more SQL queries using GUI 136 of workstation 110. Workstation 110 may communicate message 126 to data processing environment 130. Message 126 may include the file location of a file containing one or more comparison SQL queries. In response, comparison module 112 may access the file containing the one or more comparison SQL queries. Comparison module 112 may then instruct GUI 136 to display the one or more SQL queries contained in the file at the specified location. A user can use GUI 136 to select one or more comparison SQL queries to compare the source data to the target data. For example, a user may use GUI 136 of workstation 110 to specify one or more comparison SQL queries. Workstation 110 may then communicate message 126 to data processing environment 130, message 126 including the one or more comparison SQL queries.

At step 616, comparison module 112 may determine whether the source and target data match by executing the one or more comparison SQL queries. Furthermore, comparison module 112 may store the results of the comparisons in memory 104 or any other storage location suitable for a particular purpose.

FIG. 7 illustrates an example method for reporting comparison results. The example method of FIG. 7 may be performed by example data verification system 100 of FIG. 1 according to certain embodiments of the present disclosure. The method may be implemented in any suitable combination of software, firmware, and hardware. Although particular components may be identified as performing particular steps, the present disclosure contemplates any suitable components performing the steps according to particular needs.

The example method begins at step 700. After one or more functions have been performed by data processing environment 130, data processing environment 130 may provide results to a user via reporting module 114. Reporting module 114 may determine whether the destination for the results report is a database or a file. If reporting module 114 determines that the destination is a file, the example method may proceed to step 702. Otherwise, the example method may proceed to step 704. At step 702, a user may use GUI 136 of workstation 110 to input a file location to store results generated by a component of data processing environment 130. Workstation 110 may communicate message 126 to data processing environment 130. Message 126 may contain a location of a file where results should be stored.

At step 708, a user may use GUI 136 of workstation 110 to specify that the results generated by a component of data processing environment 130 should be emailed to a particular email address. A user may input the email address using GUI 136 or the user may instruct data processing environment 130 to use an email address stored in a configuration file. Workstation 110 may then communicate message 126 over network 120 to data processing environment 130. Message 126 may contain a user's preference for email reporting.

At step 710, a particular functionality of data processing environment 130 is executed and results are generated. At step 712, reporting module 114 may determine whether the generated results report is bound for a database. If the report destination is not a database, the example method may proceed to step 716. Otherwise the example method proceeds to step 714. At step 714, a user may have specified target database 150 as the destination to store results generated by a component of data processing environment 130. Reporting module 114 may retrieve destination information for the destination database. The example method may then proceed to step 716.

At step 716, reporting module 114 may store the generated results. For example, reporting module 114 may communicate message 118 over network 140 to target database 150. Message 118 may contain the results of a function implemented by data processing environment 130. In certain embodiments, message 118 may simply contain user preferences for reporting results generated by a component of data processing environment 130. According to some embodiments, the generated results may be stored in a file at a location specified by a user.

FIG. 8 illustrates an example method for updating and verifying data. The example method of FIG. 8 may be performed by example data verification system 100 of FIG. 1 according to certain embodiments of the present disclosure. The method may be implemented in any suitable combination of software, firmware, and hardware. Although particular components may be identified as performing particular steps, the present disclosure contemplates any suitable components performing the steps according to particular needs.

The example method may begin at step 800. Data update and verification module may receive table information regarding a table and a database that might store a portion of data. In certain embodiments, a user may use GUI 136 of workstation 110 to specify a particular table that is the target location for storing certain data. Workstation 110 may communicate message 126 to data processing environment 130. Message 126 may contain information regarding a table which is the destination for storing data. At step 802, in response to message 126, data update and verification module 116 may access the table and retrieve the structure of the table. For example, data update and verification module 116 may communicate message 118 over network 140 to target database 150. Message 118 may comprise a request to access the table specified by the user. In response to message 118, data update and verification module 116 may have access to database 150. At step 804, data update and verification module 116 may communicate message 126 to workstation 110. Message 126 may contain information regarding the structure of the destination table. In response to message 126, GUI 136 may present a list of columns of the destination table to a user for selection of a particular column.

At step 806, a user may use GUI 136 to choose particular columns of data for data processing environment 130 to retrieve. Workstation 110 may communicate message 126 over network 120 to data processing environment 130, message 126 containing columns of the destination table selected by the user. At step 808, data update and verification module 116 may communicate message 118 over network 140 to target database 150. Message 118 may comprise a request to access the portions of database 150 containing the selected columns. In response to message 118, data update and verification module 116 may then have access to the data contained in the selected columns of target database 150. At step 810, data update and verification module 116 may communicate message 126 to workstation 110. Message 126 may be a request to display the data in the selected columns in GUI 136. In response to message 126, GUI 136 may display the data of the selected columns of target database 150. In certain embodiments, this data may be presented as rows and columns with each intersection of a row and a column forming a cell of data. At step 812, a user may intend to repeat the process to add data from one or more columns of additional tables in target database 150. If that is the case, the example method may return to step 800. Otherwise, the example method may proceed to step 814.

At step 814, a user may begin to select particular cells of data to update. For example, a user may use GUI 136 to select one or more cells of data to update. After selecting one or more cells, the user may enter a value that should replace the current value held in those particular cells. Workstation 110 may communicate message 126 to data processing environment 130 after the user finishes entering data to replace the data currently held in the selected cells. Message 126 may contain a reference to the particular cells that the user wants to update and the particular data that the user wants to store in those selected cells.

At step 816, data processing and verification module 116 may determine whether the data should be inserted into a database or a file. In certain embodiments, a user may want to store a set of data that may be the expected results of a particular process. In such an embodiment, a user may use GUI 136 to communicate to data processing environment 130 that the data being entered into GUI 136 is intended to be set as the expected results data. Expected results data may be any data that is deemed to be “correct” data. Data processing environment 130 may then compare a particular set of data against the expected results data to determine whether the particular set of data is “correct” as well. Expected results may be stored in target database 150. In certain embodiments, if the data being stored by the user is not intended to be the expected result, data update and verification module 116 may store the data updates in an external file. If the data is intended to be stored in a database, the example method proceeds to step 818. Otherwise, the example method may proceed to step 820. At step 818, data update and verification module may communicate message 118 to target database 150 to update the selected cells according to the user's input. The example method may proceed to step 822. At step 820, data update and verification module 116 may write the results into a file corresponding to the database structure of target database 150.

At step 822, the example method determines whether particular data is intended to be verified. For example, a user may use GUI 136 of workstation 110 to initiate verification of particular data. If no verification is requested, the example method may end. Otherwise, the example method may proceed to step 824. At step 824, data update and verification module 116 may compare the data in this file to the data of target database 150 which contains the expected results data. If the data in the external file matches the expected results data held in target database 150, then data update and verification module 116 may deem the data in that file verified. At step 826, data update and verification module 116 may output the results of this verification. In certain embodiments, data update and verification module 116 may communicate these results using reporting module 114.
